FAQ's

How NB-IoT devices synchronize over cell?

Following “3GPP TS 36.300” and “Rohde-Schwarz in a white paper in web link: (www.rohde-schwarz.com/appnote/ 1MA266)”, LTE concept of Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) is reused in order for a first synchronization in frame and subframe and in order to determine the NCellID. With these signals, also timing and frequency estimation may be refined in the UE receiver. In order to distinguish these signals from their LTE counterparts, they are denoted as NPSS and NSSS, respectively.

How are Synchronization signals implemented in NB-IoT?

Following “3GPP TS 36.211 V13.2.0, June 2016; Physical channels and modulation” and “Rohde-Schwarz in a white paper in web link: (www.rohde-schwarz.com/appnote/ 1MA266)”, OFDM in DL is applied using a 15 kHz subcarrier spacing with normal cyclic prefix (CP). Each of the OFDM symbols consists of 12 subcarrier occupying this way the bandwitdh of 180 kHz. Seven OFDMA symbols are bundled into one slot. The first 3 OFDM symbols are left out, because they may carry the PDCCH in LTE when NB-IoT is operated in the in-band mode. Note that during the time when the UE synchronizes to the NPSS and NSSS, it may not know the operation mode, consequently this guard time applies to all modes. In addition, both synchronization signals are punctured by the LTE's CRS. It is not specified, which of the antenna ports is used for the synchronization signals, this may even change between any two SFs. A length 11 Zadoff-Chu sequence in frequency domain is taken for the sequence generation of the NPSS. This sequence is fixed and therefore carries no information about the cell. It is transmitted in SF5 of each radio frame, so that its reception allows the UE to determine the frame boundary. The NSSS sequence is generated from a length-131 frequency domain Zadoff-Chu sequence, binary scrambled and cyclically shifted depending on the radio frame number. NCellID is an additional input parameter so that it can be derived from the sequence. Like in LTE, 504 PCI values are defined. NSSS are transmitted in the last SF of each even numbered radio frame.
